Erectile Dysfunction and ED

Erectile dysfunction is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Erectile dysfunction is indicated when an erection is difficult to produce. There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water. The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects.

Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this is somewhat less frequent but often can be helped. Notably in psychological impotence, there is a strong response to placebo treatment. Erectile dysfunction, tied closely as it is about ideas of physical well being, can have severe psychological consequences. Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs (the first of which was sildenafil or Viagra). In some cases, treatment can involve prostaglandin tablets in the urethra, injections into the penis, a penile prosthesis, a penis pump or vascular reconstructive surgery. The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms. The study of erectile dysfunction within medicine is covered by andrology, a sub-field within urology.

Erectile Dysfunction Pathophysiology

Penile erection is managed by two different mechanisms. The first one is the reflex erection, which is achieved by directly touching the penile shaft. The second is the psychogenic erection, which is achieved by erotic or emotional stimuli. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. In both conditions, an intact neural system is required for a successful and complete erection. Stimulation of penile shaft by the nervous system leads to the secretion of nitric oxide (NO), which causes the relaxation of smooth muscles of corpora cavernosa (the main erectile tissue of penis), and subsequently penile erection. Additionally, adequate levels of testosterone (produced by the testes) and an intact pituitary gland are required for the development of a healthy erectile system. As can be understood from the mechanisms of a normal erection, impotence may develop due to hormonal deficiency, disorders of the neural system, lack of adequate penile blood supply or psychological problems. Restriction of blood flow can arise from impaired endothelial function due to the usual causes associated with coronary artery disease, but can also be caused by prolonged exposure to bright light.

Libido

Libido refers to a person's sex drive or desire for sexual activity. The desire for sex is an aspect of a person's sexuality, but varies enormously from one person to another, and it also varies depending on circumstances at a particular time. A person who has extremely frequent or a suddenly increased sex drive may be experiencing hypersexuality. Sex drive has usually biological, psychological, and social components. Biologically, levels of hormones such as testosterone are believed to affect sex drive; social factors, such as work and family, also have an impact; as do internal psychological factors, like personality and stress. There is no measure of what is a healthy level for sex. Sex drive may be affected by medical conditions, medications, lifestyle and relationship issues.

There is no necessary correlation between the desire for sex and actual sexual activity. For example, a person may have a desire for sex but not have the opportunity to act on that desire, or may on personal, moral or religious reasons refrain from acting on the urge. Psychologically, a person's urge can be repressed or sublimated. On the other hand, a person can engage in sexual activity without an actual desire for it.

The concept of libido was first introduced by Sigmund Freud as the instinct energy or force, contained in what Freud called the id. Carl Jung defined libido as the free creative or psychic energy an individual has to put toward personal development or individuation. Within the category of sexual behavior, libido would fall under the appetitive phase wherein an individual will usually undergo certain behaviors in order to gain access to a mate.

Inhibited Sexual Desire

Inhibited sexual desire (ISD) refers to a low level of sexual interest. A person with ISD will not start, or respond to their partner's desire for, sexual activity.

ISD can be primary (in which the person has never felt much sexual desire or interest), or secondary (in which the person used to feel sexual desire, but no longer does).

ISD can also relate to the partner (the person with ISD is interested in other people, but not his or her partner), or it can be general ( the person with ISD isn't sexually interested in anyone). In the extreme form of sexual aversion, the person not only lacks sexual desire, but may find sex repulsive.

Sometimes, the sexual desire is not inhibited. The two partners have different sexual interest levels, even though both of their interest levels are within the normal range.

Someone can claim that his or her partner has ISD, when in fact they have overactive sexual desire and are very demanding sexually.

Inhibited Sexual Desire Causes

ISD is a very common sexual disorder. Often it occurs when one partner does not feel intimate or close to the other.

Communication problems, lack of affection, power struggles and conflicts, and not having enough time alone together are common factors. ISD also can occur in people who've had a very strict upbringing concerning sex, negative attitudes toward sex, or traumatic sexual experiences (such as rape, incest, or sexual abuse).

Illnesses and some medications can also contribute to ISD, especially when they cause fatigue, pain, or general feelings of malaise. A lack of certain hormones can sometimes be involved. Psychological conditions such as depression and excess stress can dampen sexual interest. Hormonal changes can also affect libido.

Commonly overlooked factors include insomnia or lack of sleep, which lead to fatigue. ISD can also be associated with other sexual problems, and sometimes can be caused by them. For example, the woman who is unable to have an orgasm or has pain with intercourse, or the man who has erection problems (impotence) or retarded ejaculation can lose interest in sex because they associate it with failure or it does not feel good.

People who were victims of childhood sexual abuse or rape, and those whose marriages lack emotional intimacy are especially at risk for ISD.

Sexuality

Sexuality is a big part of being human. Love, affection and sexual intimacy all play a role in healthy relationships. They also contribute to your sense of well-being. A number of disorders can affect the ability to have or enjoy sex in both men and women. Concerns about infertility or fear of unplanned pregnancy can also come into play.

In addition, a number of diseases and disorders affect sexual health. These include sexually transmitted diseases and cancer. In men, treatment of prostate cancer can cause erectile dysfunction. In women, cervical, uterine, vaginal, vulvar or ovarian cancer may have sexual effects.
